Description
Key features of the MAX811REUS include a reset threshold voltage of 4.63V, an active-low reset output, and a push-pull output stage. It is designed to provide a reset signal when the monitored voltage drops below the threshold, signaling the microprocessor to reset and return to a known state. This is crucial for applications where consistent and reliable system performance is necessary, such as in embedded systems, automotive electronics, and industrial control systems.
The MAX811REUS comes in a small SOT-143 package, making it suitable for space-constrained applications. Its simplicity and effectiveness make it a popular choice for ensuring system stability and reliability.
Equivalent
1. MCP130T-450I/TT from Microchip
2. TPS3839K33DBVR from Texas Instruments
3. ADM811RART from Analog Devices
4. STM706R from STMicroelectronics
These alternatives offer similar functionality, typically including a reset function triggered by falling power supply voltages. Always verify specifications like voltage thresholds and timing characteristics to ensure compatibility with your application.
Features
1. Reset Functionality: It provides a reset output to ensure the microprocessor comes out of reset in a known state when power is applied or when the supply voltage falls below a preset threshold.
2. Voltage Monitoring: It monitors the supply voltage and triggers a reset when it falls below a specified level.
3. Reset Timeout: The device features a fixed reset timeout period, typically around 140ms, ensuring the system has enough time to stabilize before resuming operations after a reset.
4. Low Supply Current: It operates with minimal power consumption, ideal for battery-powered applications.
5. Manual Reset Capability: Includes a manual reset input, allowing for an external push-button or control signal to trigger a reset.
6. Small Package: The MAX811REUS is available in a small, surface-mount SOT-143 package, making it suitable for space-constrained applications.
These features make the MAX811REUS ideal for ensuring reliable performance in embedded systems by protecting against power supply disruptions.
Pinout
The pins are generally assigned as follows:
1. GND - Ground connection.
2. VCC - Power supply voltage input.
3. RESET - Active-low reset output, which triggers when VCC falls below the specified threshold.
4. N.C. (No Connection) - Typically not connected to the internal circuitry.
This setup helps maintain proper system startup and shutdown protocols, preventing undefined states in microprocessor operations.
